DIAMOND BAR, Calif. --

Six people were killed after a wrong-way driver smashed into two vehicles on the westbound 60 Freeway in Diamond Bar Sunday morning.

The driver, identified as Olivia Carolee Culbreath, 21, of Fontana, was arrested on suspicion of DUI and manslaughter following the crash.

According to CHP officer Rodrigo Jimenez, officials began receiving calls from witnesses regarding a wrong-way driver traveling in a Chevrolet Camaro on the 57 Freeway.

Shortly after, additional calls came in regarding the wrong-way driver traveling within the westbound lanes of the 60 Freeway.

That's when, Jimenez says, the Chevrolet Camaro struck a red Ford Explorer. The Explorer then subsequently struck a gray Ford Freestyle near Phillips Ranch Road around 4:40 a.m. All lanes near the exit were shut following the accident.

"We received additional calls after the collision of the parties that were ejected," said Jimenez. "We responded quickly and tried to get here as soon as we can to prevent more collisions from occurring."

The Ford Explorer was cut in half. The Ford Freestyle was also heavily damaged.

Five females, two who were 24-years-old, and a 47-year-old man were pronounced dead at the scene. The coroner has not yet released the identities of the victims who were killed.

Joel Cortez, 57, of Ontario, escaped with scratches and severe bruises. His son, Jonathan Cortez, says he is in a lot of pain.

"All he remembers really is just the airbag going off and he was just moving and moving, and finally the car came to a stop and he had looked around, and there were people like, lying on the ground, and he said it was like something you would see out of a movie," said Cortez. "We're actually really blessed to the fact that we still have him. We know that six people have been killed from this, and we send our condolences to those families and friends of the victims."

Culbreath was being treated from a broken femur and ruptured bladder at County USC Medical Center. She is, however, facing suspicion of DUI and manslaughter charges.

The investigation remains ongoing, but investigators say evidence of alcohol consumption was found at the scene.
